摘要 目的建立HPLC法测定大剂量阿糖胞苷治疗时血浆中阿糖胞苷(Ara-C)和阿糖尿苷(Ara-U)的浓度。方法反相高效液相色谱法,色谱柱:Phenomenex Fusion(4.6×150mm,4μm),流动相:0.01M磷酸盐缓冲液(pH=7.2)柱温:30℃,流速:0.8mL.min-1,检测波长:Ara-C:280nm,Ara-U:262nm。结果 Ara-C血药浓度在0.5~20μg.mL-1范围内线性良好(R=0.99),回收率为96.1~105.3%,Ara-U血药浓度在1~40μg.mL-1范围内线性良好(R=0.99),回收率为97.2~104.7%,日间、日内RSD小于5%和10%。结论本方法简便、快速,适合用于临床血药浓度监测和药动学研究。
